Children with chronic kidney disease (CKD) are affected by cardiovascular complications, including disturbances in the intraventricular conduction system. Body surface potential mapping (BSPM) is a non-invasive method of assessing the cardioelectrical field. Our aim was to investigate conduction disturbances in young CKD patients using ventricular activation time (VAT) maps. Our study comprised 22 CKD children (mean age: 13.1 ± 2.5 years) treated conservatively and 29 control patients. For each child 12-lead electrocardiogram (ECG) readings were taken, and blood pressure and serum concentrations of iPTH, Pi, t-Ca, creatinine, Fe+3, ferritin, and Hb, as well as eGFR were measured. All children underwent registration in the 87-lead BSPM system, and group-mean VAT maps and a difference map, which presents statistically significant differences between the groups, were created. The VAT map distribution in CKD patients revealed abnormalities specific to left anterior fascicle block. The difference map displays the areas of intergroup VAT changes, which are of discriminative value in detecting intraventricular conduction disturbances. Intraventricular conduction impairments in the left bundle branch may occur in children with CKD. BSPM enables conduction disturbances in CKD children to be detected earlier than using 12-lead ECG. The difference map derived from the group-mean isochrone maps precisely localizes the sites of disturbed conduction in the heart intraventricular conduction system.

“…The previous studies on BSPM has also demonstrated the similarly prolonged duration of ventricular depolarization in BSPM, and the rich information of the BSPM provided valuable diagnostic power on BBB (11). A recent study suggested even higher sensitivity of BSPM on diagnosing BBB than 12-lead ECG, showing distinctive QRS-T integral maps in patients on dialysis (12). In the current study, the end points of P-BSPM vector potential during the ventricular depolarization demonstrated the intuitively discernible patterns in BBB patients: clockwise rotation in patients with RBBB and counterclockwise rotation in patients with LBBB.…”

Using 49 capacitive-coupled electrodes, mattress-type harness was developed to obtain posterior body surface potential map (P-BSPM) in dressed individuals. The aim of this study was to investigate how valuable information P-BSPM could provide, especially in discrimination of old myocardial infarction (OMI). P-BSPM of 59 individuals were analyzed; 23 normal control, 11 right bundle branch block (RBBB), 3 left bundle branch block (LBBB) and 19 OMI patients. Principal component analysis and linear hyper-plane approach were used to evaluate diagnostic performance. The axes of P-BSPM vector potential corresponded well with 12-lead electrocardiogram. During QRS, the end point of P-BSPM vector potential demonstrated characteristic clockwise rotation in RBBB, and counterclockwise rotation in LBBB patients. In OMI, initial negativity on P-BSPM during QRS was more frequently located at lower half, and also stronger in patients with inferior myocardial infarction (MI). The area under the receiver-operating characteristic curve of P-BSPM during QRS in diagnosing overall OMI, anterior MI, and inferior MI was 0.83 (95% confidence interval, 0.70-0.97), 0.71 (0.47-0.94), and 0.98 (0.94-1.0), respectively (P = 0.022 for anterior vs inferior MI groups). In conclusion, the novel P-BSPM provides detailed information for cardiac electrical dynamics and is applicable to diagnosing OMI, especially inferior myocardial infarction.

“…BSPM is a sensitive method for detecting disturbances in the heart conduction system as compared to 12‐lead ECG examination. BSPM advantage over standard ECG recordings is caused by its unique spatial resolution and has been proven by many authors in various clinical conditions (4–10, 17–21).…”

Aim of the study was to assess the effect of KT on heart conduction in HD children. Non-invasive electrocardiographic method of BSPM was used. Isochrone maps, presenting a VAT distribution, were taken from eight HD patients and 26 normal subjects. Patients were divided into two groups: I--three children were HD <12 months prior to KT; II--five children were HD >12 months prior to KT. After KT, the groups were marked as IP and IIP. Serum iPTH and phosphate levels were significantly higher in both HD groups than in controls, with a considerable normalization after transplantation. HD patients demonstrated neither conduction abnormalities on ECG nor left ventricular hypertrophy. Group-mean VAT maps revealed: I and II--similar patterns of complete LBBB; IP--partial normalization to a pattern of anterior fascicle block; IIP--preserved pattern of LBBB. Intraventricular conduction disturbances found in HD children using BSPM were alleviated by KT. Short HD therapy increases a chance of conduction disturbances regression after KT, contrary to the longer HD treatment. BSPM is more sensitive than standard ECG in detecting heart conduction impairments in the HD patients.
